Makes you wonder why all those "tuner" kids are using Co2/Nitrous oxide to spray on their intercoolers

Sure. I was spraying water on 2 different days at 2 different types of dyno. Spraying was done on the intercooler with a stream (worse case).
On the dynojet, I sprayed first and consistantly got 12-14 RWHP at 327 RWHP level.
On the mustang dyno, I sprayed after dry runs and got 12-14 RWHP at 380+/- RWHP level.
I did this just to see if it was worth installing. I am currently installing. 100 PSI with VERY high quality misting jets and duty-cycle solenoid.
When this is finalized, I will plumb INSIDE the airstream (controled by different map but with the same hardware) and test it on the dyno.

Sameer - no. I am using custom components. Store bought kits are not good enough. I am using a large 100 psi pump, and a high quality solenoid that is fit to be controlled by a duty-cycle (load, not just RPM) 3-D engine map.
These can be found at industrial supply.
Power & ground to standard Bosch 5-pin relay direct from batt.
Switch 12volt signal from arm switch in cabin to relay.
12 volt feed from relay to pump and solenoid
ground from relay to PUMP ONLY
switched ground from cab (duty cycle) to ground solenoid.
Pump has a very fast pressure-kill internal switch.

Also - I should mention that in my case, the pump is in front and the tank is in the rear for weight distribution purposes.
Because of this, the pump has a siphon lag time. Ordinarily,this is no problem - BUT because we are using a high quality solenoid AFTER the pump, the pump can vapor-lock from lack of vent to pull the water up.
What I have done is installed an alternate purge ground for the solenoid, so that when I fill the tank, I can open the solenoid and the pump simultaneously to pressurize to ensure that water is at the jet the FIRST time it is called for.
Cliff notes - ya needs a purge switch

Here's a question. Why not just buy some dry ice and dump it into the Inter Cooler Intakes (I have a 996TT with GT-2 Intercoolers) before you go out and run? It would seem to be about as effective? Also no plumbing and no having to remember to push the putton or refill the reservoir.......

My aim with intercooler spraying is to use it where ever I need it, at any time. You can't exactly pick up dry ice at the local gas station when you have the urge to push the car hard on the way home.

I am going to be running 50/50 water/alcohol injection! Not just on my intercooler, but injection.
Theres water, alcohol, methanol, propane and toulene at the farthest end of the spectrum.
Some change your octane slightly, others cool, some chemically intercool/supercool.
They all have their advantages and disadvantages.
I'm going to run it on my 1.3l 13BT RX-7 as a safety precaution as I don't have the leisure of pinging. One detonation can kill my semi-fragile turbo rotary.

In the VAG communitiy water misting is very common and has been proven to gain 8-15 hp depending on the solution used and the turbo used. Most are using the cheap washer nozzles and are getting close to 8-9hp. Those that invest a little more and get better misting solutions see more results.
There is a great artical in AutoSpeed on how to do these: http://autospeed.drive.com.au/cms/A_0534/article.html
